AfterVideoPreviewFetchedEvent

New in version 12.2

The purpose of the PSR-14 event \TYPO3\CMS\Core\Resource\OnlineMedia\Event\AfterVideoPreviewFetchedEvent is to modify the preview file of online media previews (like YouTube and Vimeo). If, for example, a processed file is bad (blank or outdated), this event can be used to modify and/or update the preview file.

Example

EXT:my_extension/Configuration/Services.yaml

  # Place here the default dependency injection configuration

  MyVendor\MyExtension\Resource\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/after-video-preview-fetched'
